This is usually fertilized by direct contact with the antheridium, and from it, more or less di- rectly, are produced the spore-sacs or asci.

THE FUNGI WHICH CAUSE PLANT DISEASE 117 The oogonium after fertilization gives rise to a more or less complicated system of ascogenous hyphae, very simple in the Erysiphaceae, very complex in some Discomycetes, which produces the asci. The sterile parts of the ascocarp, the paraphyses and enveloping structures, arise from parts below the oogonium and antheridium. The very young ascus usually receives two nuclei from the parent strand of the ascogenous hypha. These nuclei unite giving the. Please note that these images are extracted
